Further, a digital recording of a vocal utterance made by a user may be captured. The vocal utterance may be interpreted based on the stored user interaction information. An intent of the user may be identified based on the interpretation, and a prediction may be made based on the identified intent. The prediction may further correspond to a selected workflow.

BACKGROUND 1. Field of the Invention

The present technology pertains to natural language processing, and more specifically to learning models for natural language processing based on network (e.g., game network) interaction.

2. Description of the Related Art

Current content platforms may provide a access to a wide variety of content and options related to such content. As a result, such platforms may be complicated to configure, set up, and navigate. While vocal commands may be used, such vocal commands may likewise require complex or complicated workflows corresponding to the traditional workflow. Players of a game, for example, may use a user device 120 to access the game, which may be hosted on network server 130. The game may be played with other players in the network. For example, player A may wish to play a game with her friends, player B and player C. To execute the same using traditional workflow, the player may need to select the game (e.g., which may include scrolling through a list of players), designating that an invitation be sent to player B (e.g., which may include scrolling through a list of players), and designating that an invitation be sent to player C. Verbally requesting that each step be performed may not necessarily be any more efficient. The use of vocal commands may therefore be as slow as, if not slower than, the traditional workflow.

There is, therefore, a need in the art for systems and methods of network-based learning models for natural language processing.

DETAILED DESCRIPTION

Embodiments of the present invention include systems and methods of network-based learning models for natural language processing. Information may be stored information in memory regarding user interaction with network content. Further, a digital recording of a vocal utterance made by a user may be captured. The words and parts of speech that make up the vocal utterance may be identified based on natural language processing models. Such words may further be interpreted based on contextual information such as the stored user interaction information. An intent of the user may be identified based on the interpretation, and a prediction may be made based on the identified intent. The prediction may further correspond to a selected workflow.

In a content network, some content interaction may further have a social element. Games, for example, may be played with one or more social contacts. During the course of such games, interaction with the other players may involve “trash talk” and other conversations directly or indirectly related to the content.

FIG. 1 illustrates a network environment 100 in which a system for social-based management of content may be implemented. The network environment 100 may include a communication network 110 through which one or more client devices 120A-C may communicate with network server 130 and third party systems 140.

Communication network 110 is preferably a local, proprietary network (e.g., an intranet) and/or is alternatively a part of a larger wide-area network (e.g., the cloud). Communications network 110 can be a local area network (LAN), which is communicatively coupled to a wide area network (WAN) such as the Internet. The Internet is a broad network of interconnected computers and servers allowing for the transmission and exchange of Internet Protocol (IP) data between users connected through a network service provider. Examples of network service providers are the public switched telephone network, a cable service provider, a provider of digital subscriber line (DSL) services, or a satellite service provider. Communications network 110 allows for communication between the various components of network environment 100.

Users may use any number of different electronic computing devices 120A-C, which can include, but is not limited to, general purpose computers, mobile phones, smartphones, personal digital assistants (PDAs), portable computing devices (e.g., laptop, netbook, tablets), desktop computing devices, handheld computing devices, tablet devices, game consoles, smart televisions, or any other type of computing device capable of communicating over communication network 110. Such devices 120A-C are preferably configured to access data from other storage media, such as, but not limited to memory cards or disk drives as may be appropriate in the case of downloaded services. Such devices 120A-C preferably include standard hardware computing components such as, but not limited to network and media interfaces, non-transitory computer-readable storage (memory), and processors for executing instructions that may be stored in memory. An exemplary computing device 120 is further illustrated and described with respect to FIG. 4. In some embodiments, the computing device 120 may be associated with peripheral devices (e.g., microphone on voice switch headset) and software (e.g., messaging applications) by which user input may be captured.

Network server 130 may include any type of server or other computing device as is known in the art, including standard hardware computing components such as network and media interfaces, non-transitory computer-readable storage (memory), and processors for executing instructions or accessing information that may be stored in memory. The functionalities of multiple servers may be integrated into a single server. Any of the aforementioned servers (or an integrated server) may take on certain client-side, cache, or proxy server characteristics. These characteristics may depend on the particular network placement of the server or certain configurations of the server.

Network server 130 may host a variety of digital media content available to user devices 120 in the network environment 100. Each user (e.g., of user device 120) may be associated with an account that allows the user to access his or her library of content. Such content may be interactive content that allows for interaction by the user, as well as others. A game, for example, may be played simultaneously by multiple players, as well as involve interaction amongst the players.

Third party systems 140 may provide any of a variety of resources to network server 130 to assist with natural language processing, interpretation, and identification of user intent. Such resources may provide information regarding specific contexts (e.g., in handling requests for games) with which the utterances are related.

Because network server 130 hosts the content, network server 130 may monitor and track a variety of user interaction involving such content. Such interaction may involve network content, as well as interaction with social contacts. Such interaction may include behaviors, communications exchanged, actions taken, events taking place, milestones reached (e.g., points, levels, trophies, achievements, etc.), and other identifiable reactions to the content and/or to the social contacts. In addition, content server 130 may track the details of the content title (e.g., a specific game) with which the user interacts, including genre, developer, play requirements (e.g., number of team members, roles of team members), etc.

Learning models for customized workflows may be developed based on user activity (e.g., content and social interaction) within the network to allow for predictive selection of a workflow. As such, network server 130 may track information regarding user interaction within the network. Such interaction may involve network content, as well as interaction with social contacts. Tracked interaction information may reveal patterns of behavior and trends that may be specific to certain content titles, certain content title genres, certain social circles, and other contexts in which the interaction occurs. The learning models may be developed over time and may rely in part on resources and information provided by third party services 140.

In addition, network server 130 may further store information regarding social contacts with whom the user interacts. Such social contacts, who are also users within the network environment 100, may be designated by the user as such. In some embodiments, the user may further characterize the social contact by degree of familiarity, types of shared activities, types of content in common, common interests, defined teams or clans (which may or may not be specific to a title), or any other category. The social contact may also be associated with a variety of other parameters that may be used to characterize that contact, including demographic data, community membership, respective content titles in his or her library, how often a content title is played, etc.

A microphone associated with user device 120 may capture vocal utterances during the course of such user interaction. Network server 130 may analyze a digital recording of the vocal utterance in context with the current user interaction, as well as past user interactions that may share some commonalities. Such analysis may include decoding the digital recording, transcribing the vocal utterance, evaluating the words of the vocal utterance to identify keywords or other indicators of intent, identifying one or more possible interpretations, and narrowing the possible interpretations based on the context of the user interaction information. Each interpretation may further be associated with a different intent to proceed with a particular workflow. Network server 130 may then make a prediction as to which workflow the user wishes to select based on interpretation of the vocal utterance.

FIG. 2 illustrates an exemplary server 200 that may be used in network-based learning models for natural language processing. While a server 200 may include a variety of standard hardware as described above with respect to network server 130, network-based learning models for natural language processing may further involve more specialized components, such as automatic speech recognition 210, voice-to-text 220, natural language processor coordination 230, agent dispatcher 240 (including condition-action rules 250A and action workflows 250B), learning models 260, and a prediction engine 270.

Automatic speech recognition 210 allows for decoding of digital audio recording, such as a digital recording of a user utterance. Such utterance may be captured as an mp3 file, for example, though any digital audio format (e.g., streamed audio) may be used. Voice-to-text 220 may be inclusive of any transcription application known in the art for analyzing a digital recording, identifying any words spoken, and generating text based on the identified words.

Natural language processor coordination 230 may be inclusive of any processor that can make use of artificial intelligence, filters, classifiers, machine learning techniques, etc. to evaluate an expression of natural language. Such a natural language processor coordination 230—which may be informed by information stored in learning models 260—allows network server 200 to narrow down the possible interpretations of a vocal utterance made by the user and to identify a more specific intent of the user in making that vocal utterance. In some embodiments, natural language processor 230 may weight various factors in identifying which specific intent is meant by the user, including how recently the interaction occurred, how often, with whom (e.g., social contact), characteristics of the content or social content, and identifiable patterns and trends. Natural language processor coordination 230 may further make use of various third party services 140 to assist with interpretation of the words spoken by the user and with identification of intent in different contexts.

Agent dispatcher 240 may manage such third party services 140, specifically identifying which third party services 140 to call on for assistance with a particular task or request. Agent dispatcher 240 may further manage workflows 250 associated with certain condition-action rules 250A and responsive actions 250B to be performed in relation to content interaction. For example, in the context of games, such workflows 250 may relate to various game-related activities (e.g., assembling teams for gameplay). Each workflow 250 may include one or more condition-action rules 250A used to identify which actions 250B (e.g., tasks and steps) are involved in engaging in the activity. Each task and step may require certain information (e.g., inputs) from the user, however. For example, assembling a team may require that the user select one or more team members. Each workflow may include pluggable code used to call on one or more functions and services in a manner customized to the specific user.

As illustrated, various inputs may be received (e.g., from sensors and interfaces detecting conditions in the environment, including user actions) and evaluated in view of condition-action rules 250A. Such evaluation may result in finding that a particular responsive action (e.g., from actions 250B) is to be performed. Information regarding the selected action may then be provided to designated actuators or other actors for execution or performance.

The learning models 260 for interpreting utterances by the user and identifying responsive workflows may be stored and refined over time as data is gathered regarding the user. As such, interpretations of the user utterances may improve with respect to identifying certain entities that the user may be referencing and parts of speech likely to be used by the user. The information used to refine the learning models 260 may include information regarding any variety of user interaction that may occur in the network as tracked by network server 130. Such user interactions may occur in relation to content accessed at network server 130, as well as interactions (e.g., messages sent through messaging applications and otherwise) in relation to social contacts (who also access content at network server 130). The learning models 260 may be continually updated and refined as additional user interactions occur within the network. As such, the base of information to which natural language processor coordination 230 may reference in identifying user intent may continue to grow, allowing for learning and improved recognition of user intent. As such, learning module 260 may be involved in refining the condition-action rules 250A, as well as selection of responsive actions 250B over time in a manner that may be specific to the particular user and their respective habits, networks, and other user-specific characteristics.

Prediction engine 270 may identify that the intent identified by natural language processor coordination 230 corresponds to a predetermined workflow 260. The identified intent may also provide the information needed to execute on a predetermined workflow.

FIG. 3 is a flowchart illustrating an exemplary method of network-based learning models for natural language processing. The method 300 of FIG. 3 may be embodied as executable instructions in a non-transitory computer readable storage medium including but not limited to a CD, DVD, or non-volatile memory such as a hard drive. The instructions of the storage medium may be executed by a processor (or processors) to cause various hardware components of a computing device hosting or otherwise accessing the storage medium to effectuate the method. The steps identified in FIG. 3 (and the order thereof) are exemplary and may include various alternatives, equivalents, or derivations thereof including but not limited to the order of execution of the same.

In method 300, information regarding user interaction may be tracked, a vocal utterance of the user may be captured, transcribed, parsed, and then interpreted in context with tracked interaction, an intent may be identified based on the interpretation, and a workflow selection may be predicted based on the identified intent.

In step 310, information regarding user interaction in a network may be tracked. Such interaction may occur with respect to particular content titles or particular contacts. Information regarding the particular content titles and contacts (e.g., user profiles) may also be tracked, including interaction by each contact with respect to certain content. Such information may be stored in a database, such as learning models 260, as well as in multiple different database accessible to the network server 200.

In step 320, a vocal utterance of the user may be captured. Such capture may occur via microphone at a user device 120. Such vocal utterance may further be saved as a digital recording (e.g., mp3 audio file), which may be transmitted over communication network 110 to network server 130.

In step 330, the vocal utterance may be transcribed and parse. Network server 130 may decode the digital recording (e.g., via decoder 210), as well as transcribe and parse the decoded digital recording (e.g., via speech-to-text 220) into text.

In step 340, the parsed text may be analyzed and interpreted in context of the tracked interaction information from step 310. Natural language processor 230 may identify one or more possible interpretations of the vocal utterance and reference resources from third party services 140 managed by agent dispatcher 240, as well as learning models 260, to narrow down the possibilities.

In step 350, an intent may be identified based on the interpretation. Such an identification may be made by natural language processor coordination 230 based on weighting of various factors, which may include reference to learning models 260, as well as any other databases that may maintain information regarding the users and content in the network. Such weighting may be based on characteristics of the content or social content and may be adjusted over time as additional information is tracked.

In step 360, a prediction may be made as to a workflow selection. Prediction engine 270 may identify that the intent identified by natural language processor coordination 230 in step 350 corresponds to a workflow stored in workflows 260.
